If you can't connect you won't be able to backup...but I gathered the BlackBerry is new to you and doesn't have anything of yours on it anyway, right?

See the two articles at blackberryfaq.com on using JL_CMDR. That will be helpful if you conclude you need to wipe the device first. But read the directions on using loader.exe instead of desktop manager.

I don't have opinions on OS versions. You can use the latest version released by you carrier, or just go with the latest official release for your model posted in the sticky on the forum.Posted via BlackBerryForums.com Mobile
